FRUIT-JAR.

SPECIFICATION forming part of Letters Patent No. 279,535, dated June 19,1883, Application filed April 10, 1853. (No model.)

- To all whom it may concern:

Be it known that I, HARRY CAIN, a citizen of the United States, residingat Bridgeton, in the county of Cumberland and State of New Jersey, haveinvented a new and useful Fruit- Jar, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to fruit-jars; and it has for its object toprovide a simple, inexpensive, and efficient self-sealing jar, which isspecially applicable to meet the requirements of packers and dealers infancy canned goods.

Heretofore self-sealing jars have been constructed in a great variety;but, as a rule, they have been devised with special reference to theiruse in families. My improvements render the jars no less desirable fordomestic use; but at the same time they are especially intended to morefully meet the requirements of dealers in canned goods than hasheretoforev been attained with any j ar of this class of which I amaware.

To these ends my invention consists in, certain novel constructions andarrangements of parts, as will be hereinafter fully set forth, andparticularly pointed out in the claims.

Inthe accompanying drawings, Figure 1 represents a perspective view of ajar embodying my improvements. Fig. 2 represents a vertical section ofthe same, only a portion of the jar in this view being shown. Fig. 3represents a detail view of the clamping-yoke. Fig. 4 represents adetail view, showing the shape of the cover 011 the under side thereof;and Fig. 5 represents a detail View of the clamping-yoke and coverplaced in position together.

Like letters refer to corresponding parts in all the figures.

Referring to the drawings, A designates the jar, composed, preferably,of glass molded in any desired forni. A circumferential groove, (1, isformed in the upper part of the jar, along the top edge, for thereception of a packingring, b, which fits tightly around a flange, 0,extending from the top of the jar. On each side of the jar is a recessshaped like an inverted T, and this -shaped recess is for the purpose ofallowing the ends of the clampingl oke to engage with either wing of therecess and be held thereby.

G designates the recessed cover. The recess (1 of the cox'er is flaringat the outer ends, e e, and said recess forms and leaves on each side ofthe same diagonal abutting wallsff, which latter serve to guide andlimit the clamping yoke in its lIlOVGIIlGIli'S. Shoulders g y are formedat suitable distances in the rim of the cover, and are adapted .toprotect the down-' ward ends ofthe clamping-yoke from displacement.

D designates the clamping yoke or bail, 6X tending across the cover andfitting within the recess of the same. This yoke has a flat upperportion with two depending legs, each of which isprovided with fingersl1, curved inwardly and adapted to fit within the recess in the jar. Inoperation the clamping-yoke is turned from one side to the otherfand inthis movement the yoke travels abutting against the walls f f. As seen,the depending legs of the yoke abut against the shoulders g g, and thusthe legs are protected from lateral displacement, as stated. The saidyoke is preferably constructed of heavy softiron, copper, or brass wire,which will admit of the necessary bending to form the fingers of theyoke. The under side of the cover is formed convex, as at a, and theinside surface of the rim ((9 is beveled to fit nicely over the packingof the jar. The object of the convex curvature is to form an airtightjar, as will be further mentioned.

The jar is, sealed as follows: After filling the jar to its utmost thepacking-ling is placed on, then the cover. The convex under surface ofthe jar-cover, by being pressed downward, causes the superfluous juiceto be forced out over the sides of the jar. W'hile pressure is beingapplied the clamping-yoke is put on over the cover, and fitting withinthe recess of the same, the fingers sitting within the shaped recessesof the jar. Then take hold of each leg of the clamping-yoke, turning onelaterally in one direction and turning the other leg in the oppositedirection. By this turning, one of the curved fingers is under theright-hand wing of one of the clamp-receiving recesses, while theotherfinger is under the left-hand wing of the opposite recess, and thusthe clamp is securely fastened and the cover sealed. The jars are thenwashed to remove the overflowovcr the flaring outer ends, 6 e, g

ing fruit-juice, and after drying they are ready for packing andtransportation. For opening the jar, the legs of the yoke are turned inthe opposite directions from what theyare now,

and the cover can then he removed.

By my method of sealing, an air-tight jar is insured, as there will beno space left in the jar, after the superfluous liquid has overflowed,for an air-space to exist. The slight trouble of washing the jars 'willbe well worth that trouble when the accomplishment of the see curing ofan air-tight jar is taken into coir SlLlGJELfiOlL It will he seen thatmy jars are very simple and inexpensive, that they can be readily andsecurely sealed, and are easily opened.

Having thus described my invention, what I claim; is- I r,

1. In fruit iars, tile combination, with the jar having vertical andlateral, recesses in its top, of a cover provided with a recess flaringoutwardly at each end, and a clamp fitting within the recess of thecover and the recesses of the jar, as set forth.

2.; In fruitjars, the. combination, with the jar having vertical andlateral recesses in its top, of the cover provided with a recess flaringoutwardly at each end, shoulders on the rim of the cover, and a clampfitting within the recess of the cover and the recesses of the jar,

'as set forth.

3. In fruit-jars, the combination, with the j ar having -shaped recessesin the top, on each side, of the cover, provided with anoutwardlyfiaring recess in its top, shoulders on the rim of the cover,and a clamp engaging with the recess in the cover, and provided withfingers engaging with the recesses in the sides of the jar, as setforth. 7

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

HARRY CAIN.
